I don't understand a word you've posted. How would I go about overclocking an ATi Radeon 4800HD just a little bit, to get consistent 30fps in BF3?
4800 what? 4830? 4850? 4870? 4890? There are substantial performance differences between them which will dictate whether or not what you want to do is possible. In addition, I believe the 4890 has more overclocking headroom than the others.

maybe consider a 560 Ti if you can budget it
A 560ti is the last card I would recommend to someone looking for BF3 performance unless they finally fixed the awful triangular artifacting?

So it's summertime, at it looks as though the thermal performance of my overclock, which I set up last summer, has gotten quite a bit worse - Last year I was under 72C during IBT in ambient temperatures up to 95F, now anything 85f for ambient temperatures is pushing me up to 78C on my hottest cores. My case is relatively dust free.

I'm thinking maybe I should try reseating my heatsink and re-applying paste. I guess these things can dry out over a year? Other than that I'm out of ideas. In the meantime I've dropped my clockspeeds back to stock and undervolted the poo poo out of my 2500K.

TIM usually won't dry out that quickly. Did you increase the voltage at some point in the last year? You may want to reseat just to verify though.

Nah, voltage hasn't been touched, been running offset of -0.045 for a core voltage of 1.24 in the BIOS. I guess I'll just reapply paste when I get a new video card (I'm dumb and buy things I don't need, 670, here I come)!
